Circle Coloring and Deletion Collection User Study

Note: A single "stroke" refers to drawing a shape without lifting the pen (or letting go of the mouse button) in the middle of drawing it.

This user study is meant to collect single-stroke sketched circles that are then either colored in or scribbled out with a second stroke. Think of it as if you are drawing in a notebook mainly for yourself to see, so you do not have to be thorough in your drawing (for instance, a colored-in circle does not need to be solid black in the center), just thorough enough that you would recognize what it was that you intended to draw if you saw it again later.

Once the applet loads, simply enter in the requested information and perform the study. If strokes do not appear when sketching, press the "Clear" button. After drawing the requested shape, simply press the "Save" button. You will be asked to draw 10 colored-in circles and 10 scribbled-out circles throughout the study. When done, simply close the window. Please do not close it until you have completed the study. Thank you for your participation!
